1/8 +0/8 =1\8
These are my answers because 1 x any number is its self and same thing for 1/8+0/8 they are the same so you dont add the denominators.
First you go the tenths place which is the number 9 stands. You look to the left of the number. Here is the tricky part if the number is under 5 for example 1 2 3 4. The number stays the same and everything behind that number is 0. If the number is 5 or higher the number goes up one and everything behind it is 0. So 3.987 rounded to the nearest tenth is 4.000
Hello!
To do this, we know the two triangles are similar, so we can set up a proportion, and then find the length of the lake.
----
The two triangles (Triangle AEB and ADC) are similar. We know this because all the angles have the same measurement - They all share angle A, they both have a right angle, and therefore, their third angle measures the same.
What we know about both triangles is their hypotenuse length. We know that triangle AEB has a hypotenuse that measures 320 m, and ADC has a hypotenuse that measures 320 + 162, or 482 m.
320 : 482 is therefore the ratio between the side lengths of two triangles (AEB : ADC). We can simplify this to 160 : 241.
Now, what we are looking for is the side length DC. The corresponding side to this in triangle AEB is EB, and we know it measures 40 m. Therefore, using the ratio, we can find the measure of DC.
160 / 4 : 241 / 4
40 : 60.25
Therefore, the measure of DC is 60.25 m.

Hope this helps!

Answer:
The loan was for 9 months only
Step-by-step explanation:
In this question, we are concerned with calculating the time taken for a loan om an interest to be paid back
To calculate this, we use the simple interest formula
Mathematically;
I = PRT/100
where P is the principal which is the amount borrowed and that is $500 according to the question
R is the rate which is 8% according to the question
Interest can be calculated by subtracting the principal from the amount paid back = 530-500 = 30$
We now plug these values into the equation
30 = (500 × 8× T)/100
100 × 30 = 4000T
T = 3000/4000
T = 0.75 (same as 0.75 × 12 months = 9 months)
